I have gone straight through most of the puzzles on conceptis. But for some reason, I cannot get through all of the easy Battleship puzzles. The 10x10 is rated "easy" as well as the 8x8. I have stared at it and started over a number of times, but I must still be missing one or more very obvious steps or techniques. I usually derive solution techniques fairly quickly, but not for the battleships. :\ Anyone have a general tip?? Thank you :)
